| description | According to the diffusion film, a continuous or discontinuous optical microstructure is arranged on a light emitting surface or/and a light incident surface of the diffusion film, and the optical microstructure is of a stacked structure. The optical microstructure at least comprises a platform; the platform is provided with a light-emitting top surface and at least one continuous light-emitting peripheral side surface; the light-emitting top surface of the platform is parallel to the light-emitting surface of the diffusion film. The light uniformizing effect is improved by providing a plurality of platforms, and the light mixing effect of the light source is improved. By the adoption of the mode, the light intensity at the center position of the LED light source emitting area can be gradually weakened through the platform, light rays are diffused outwards towards the center position of the LED light source emitting area through multiple times of reflection and refraction, and then the light intensity and the |
